1983 Honda CB450SC Nighthawk Pivot Dust Cap & Shock-Joint Bushing

The 1983 CB450SC Nighthawk rear mounting selection brings together a genuine pivot dust cap and a separately referenced shock-to-swingarm bushing. The cap has a documented Honda supersession list. The bushing has a specific three-dimension profile, so identify its mounting location without treating it as a pivot-bearing replacement.

1983 Honda CB450SC Nighthawk · Swing Arm Parts Buying guide

Use the cap reference chain and the bushing dimensions

Honda 52144-356-005 identifies the individually supplied pivot dust cap. The 40548-268-000 shock-mount bushing is also sold individually and measures 19 mm long, 22 mm outside and 10 mm inside.

Apply the supersession list only to the cap

The genuine cap replaces 52144-268-000, 52144-286-000, 52144-329-000, 52144-356-003 and 52144-965-005. Those references provide a concrete cap ordering comparison. They do not establish interchange with the separately specified shock-mount bushing or unidentified pivot components.

Inspect the pivot before deciding a cover is sufficient

The cap FAQ names the pivot bushings or bearings, inner collar, seals and pivot bolt for inspection. A new cap protects that sealing area but cannot correct worn-pivot play. Assess those parts before restricting the service order to a protective cap.

Common questions

Which earlier cap references are expressly replaced by 52144-356-005?

The cap source names 52144-268-000, 52144-286-000, 52144-329-000, 52144-356-003 and 52144-965-005. Compare the original pivot cap and its reference against that list. Use the documented chain for the cap application without extending it to other rear mounting parts.

Can I assume two of each individually sold rear mounting part are needed?

No exact 1983 CB450SC total is stated for either product. The cap listing explicitly says quantities vary by application, and the bushing is sold each. Count the matching cap and shock-joint locations separately using the correct assembly diagram.

How do I confirm the bushing when the rear suspension has been altered?

Match 40548-268-000 at the shock-to-swingarm joint and compare its 19 mm length, 22 mm outside diameter and 10 mm inside diameter. The source defines that mounting bushing; it does not establish a replacement for every altered joint or swingarm pivot bearing.
